SCREENING FOR BALANCED WINDOWS.

Specification of LettersPatent.

Patented J an. 11, 1916.

Application filed November 7, 1913. Serial No. 799,673.

To all whom it may concern Be it known that I, W'ALDo S. KELLOGG, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Screenings for Balanced Windows, of which the following is a full, clear, and eXact description.

The invention which constitutes the subject-matter of this application relates to a method of applying screens to what is commonly' known as the austral window. Briefly, this type of window consists of a pair of sashes capable of being bodily raised and lowered between the jambs of the window frame, the upper sash being provided at its top and the lower sash at its bottom with means for pivotal engagement with the jambs, and a balance lever pivoted between its ends to the frame and at its ends to the upper and lower sashes, respectively. For a detailed description of the austraL-and what is sometimes called a balanced -window, I refer to the patent to Abell, No. 14,408, reissued November 14, 1905, and the patent to Knox, No. 821,510, granted May 22, 1906.

The chief object of the invention is to provide a construction in which screens may be readily applied to and removed from the jamb which is provided with a balanced window, without in any way affecting the normal opening and closing of the windows; that is a construction in which a free rotation of the balance arm through an angle of 90 degrees is permitted, while affording a complete screeningof .the entire opening of the window frame by means of two screens in contact with the parting strips and connected between the meeting rails of the sash.

In the drawings, Figure 1 is a longitudinal section of a balanced window in closed position, showing the screen in place. Fig. 2 is a similar section, showing the screens in place, but illustrating the balanced windows in open position. Fig. 3 is a front view of the screened window with the sashes removed to illustrate the relation of the screens at their meeting rails with the-balanced arms. Fig. 4 is a similar view, showing :the appearance of the same with the lower sash in position. .Fig. 5 is a front viewofa modified form of the parts being in normal position with portions broken away .to illustratedetails. Fig. 6 is a detail 'spectively, which ,member 27 and the upper common to all the modifications. Figs. 7, 3 and 10 illustrate'further modifications of the device shown in Figs. 1 to 4 inclusive. Fig. 9 illustrates one manner in which the filler connecting the upper and lower screens may be secured to the window frame.

Referring to the drawings in detail, in which like characters refer to the same parts in all the views, and particularly to Figs. 1 to 4 and 6 inclusive, 10 and 11 designate the upper and lower-sashes, respectively, of the window located in the frame 1-2. These sashes are pivotally connected at 13 and 14 to the balance arms 15, and the latter in turn pivotally connected, as indicated at 16, to the frame or jamb 12. The upper sash is provided at its upper end with means 17 and the lower sash at its lower end with means 18 for pivotal en.- gagement with the window frame. The upper and lower screens 19 and 20 are located in the plane of the parting strips. Hence only the upper parting strip 21 is shown in Figs. 1 and 2. One of the side parting strips 22 is shown in Fig. 3. These parting strips are preferably wider than the meeting rails of the screens, so as to ac comodate the slight offset resulting from the rabbeted connection 23 between the upper and lower screens, said connection serving the purpose of a weather strip.

A space 24 is provided between the lower meeting rail of the upper sash and the upper meeting rail of the lower sash to permit the lower and upper meeting rails of the upper and lower screens, respectively,

to'be located between them, as clearly illustrated in Fig. 1. The balance arms 15, when the sashes are in closed position, lie within the plane defined by the parting strips. In fact the pivot pin at the point 16 extends through the parting strip into the frame. In order, however, to provide a housing for these balance arms, the lower end of the upper screen and the upper end of the lower screen are cut away, respectively, at the points 25 and 26. ceal these arms and also to close the opening resulting therefrom, I. provide metallic members 2.7 and 28, riveted or otherwise secured to the upper and lower screen, re-

overlap and lie against the side parting strips, as clearly indicated in Figs. 1 and 4. The lower end of the end of the mem- To conber 28 are preferably located at the same radial distance from the pivotal axis of the balance arm. It will therefore be obvious that if the pivotal point of the balance arms be provided with arcuate bosses 29 and 30 (see Fig. 6), the radius of which coincides with the radial distance aforesaid, a complete screening of the window opening is provided at all times, and at the same time the balance arms are permitted to rotate through an angle of 90.

In placing the screens in normal position the sashes l0 and 11 are thrown open preferably to about the position indicated in Fig. 2. The lower screen 20 is then placed in position from the outside the lower end of which is maintained in position preferably by means of one or more dowel pins 31 and the upper end of which is maintained in position preferably by means of screws 32 which pass through the lower members 28 and engage with the side parting strips.

The upper screen is now placed in position from the inside the grooved lower end of which engages with the grooved upper end of the lower screen to form a rabbeted connection between the two, not only to serve as a means to hold the lower end of the upper screen in place, but also to serve as a weather strip. The upper end of this screen is held in position by means of one or more suitable bolts 33. These bolts for holding these screens in place are obviously wellknown mechanical eXpedients and I will. therefore make no claims thereto 3907' so.

In Figs. 5, 6 and 7, I show the changes necessary to be made in the screens when it is desirable to have the latter abut against the sides of the parting strip instead of being located in the same plane therewith. In this case the screens are provided with the rabbeted connecting members or moldings 34 and 35 secured to the back side of the upper screen and to the front side of the lower screen in any suitable manner. For maintaining the screens in position I employ a plurality of spring-pressed or other bolts 36.

The forms of screen just described, and illustrated in Figs. 1 to 7 inclusive, are

preferable where the screens are to be used throughout the different seasons of the year. But, owing to the space 24 left between the meeting rails, they are not so desirable when they are to be removed during certain seasons, as the modified form shown in Figs. 8

- and 10, which I will now proceed to describe.

In Fig. 8 I show a connecting member or filler 37, which is permanently secured to the window jambs and is located in the plane of the parting strips. In fact,it will be quite obvious that this member serves as a parting strip for the upper end of the lower screen and the lower end of the upper *screen. It will be seen that when the upper and lower screens are removed, the member 37 remains in position to bridge the space 24 between the meeting rails of the upper and members 38, 39 on opposite sides thereof,

which are preferably secured to the opposite sides of the said parting strips, as by the set-screws shown. The lower edge of the member 38 and the upper edge of the member' 39 are located at the same radial distance from the axis of the balance arm pivot. Hence it will be seen that the arcuate bosses 29 and 30 (see Fig. 6) permit the arms to rotate 90 degrees and at the same time close the window opening as previously described. In like manner the two members 3% and 35 shown in Fig. 7 instead of being secured to the screens, may be permanently secured to the parting strips or jambs of the window frame, as illustrated in Fig. 10,

in which case it will possess substantially all of the advantages possessed by thespeinclusive, the space 24 may be closed by a suitable filler, which may be kept in stock.

It isto be understood that I do not confine myself to the exact construction or constructions described above or illustrated in the accompanying drawings, as changes may be made in point of detail, and other embodiments resorted to, without necessarily deviating from the true spir t and scope of my invention.
